Description

β-Cyclodextrin, Sulfated Sodium Salt is a chemically modified derivative of β-cyclodextrin, featuring sulfated groups that impart enhanced water solubility and anionic character. This modification is critical for applications requiring strong binding to cationic species and improved biocompatibility. It is an essential material for researchers and manufacturers in the pharmaceutical, biotechnology, and analytical chemistry sectors seeking advanced molecular encapsulation and separation solutions.

Application

• Pharmaceutical Research & Drug Delivery: Used as a solubility enhancer and stabilizer for poorly water-soluble active pharmaceutical ingredients (APIs), and in the development of controlled-release systems.
• Biochemical Separation & Purification: Acts as a chiral selector in capillary electrophoresis and HPLC for the separation and analysis of enantiomers and other complex biomolecules.
• Protein & Enzyme Stabilization: Employed to stabilize proteins, enzymes, and other labile biological compounds in diagnostic kits and bioprocessing.
• Catalysis & Chemical Synthesis: Serves as a supramolecular catalyst or a recyclable reagent scaffold in organic synthesis and green chemistry applications.
• Cosmetic & Personal Care Formulations: Functions to encapsulate fragrances, vitamins, or active ingredients, improving their stability and controlled release in final products.

Quality Control

Our β-Cyclodextrin, Sulfated Sodium Salt is produced under a rigorous quality management system. Each batch is tested to ensure consistent purity, degree of substitution (DS), and performance. Certificates of Analysis (COA) documenting key parameters are available upon request. We can support compliance requirements for research and cGMP applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area. Due to its hygroscopic (moisture-sensitive) nature, the container should be kept sealed and stored under conditions of low humidity. Recommended long-term storage at 2-8°C.
